47 // This file defines the API for messages over the pipe between the
48 // hpcrun client (hpcrun/fnbounds/fnbounds_client.c) and the new
49 // fnbounds server (server.cpp).
50 //
51 // Note: none of these structs needs to be platform-independent
52 // because they're only used between processes within a single node
53 // (same for the old server).
